Overview

The LC72725KVS is ICs that implement the signal processing required by the European Broadcasting Union RDS (Radio Data System) standard and by the US NRSC (National Radio System Committee) RBDS (Radio Broadcast Data System) standard. These ICs include band-pass filter, demodulator,and data buffer on chip. RDS data can be read out from this on-chip memory by external clock input in slave operation mode.

Functions

• Bandpass filter : Switched capacitor filter (SCF)

• RDS Demodulation : 57KHz carrier and RDS data clock regeneration, biphase decode, differential decode.

• Buffer : 128 bit (about 100ms) can be restored in the on-chip data buffer.

• Data output : Master or slave output mode can be selected.

• RDS-ID : Detect RDS signal which can be reset by RST signal input.

• Standby control : Crystal oscillator can be stopped.

• Fully adjustment free

• Low Voltage

LC72725KVS属于RF/IF，射频/中频和 RFID > RF 解调器。安森美半导体公司制造生产的LC72725KVSRF 解调器RF 解调器是设计用于从调制波中提取信号的器件，调制波则是通过使用频率、幅度、相位、放大器或位移器而改变的波。
